In laboratory environments, filtration is essential for ensuring user safety and the quality of procedures. However, many misconceptions persist about this topic, leading to unrealistic expectations or technical misunderstandings. This article aims to debunk myths about filtration and clarify what these systems can truly achieve.
Myth: Filtration eliminates 100% of contaminants
It is often assumed that filtration systems remove all contaminants in a laboratory. While these technologies are highly effective, they do have technical limitations.
Reality: Whether EPA (Efficient Particulate Air), HEPA (High-Efficiency Particulate Air), ULPA (Ultra-Low Penetration Air), or activated carbon filters, they are designed to capture the majority of harmful particles and vapors. For example, HEPA filters can retain 99.95% to 99.995% of particles larger than 0.3 µm, while ULPA filters can capture 99.9995% to 99.999995% of such particles. However, no system can guarantee absolute elimination.
How to manage expectations?
- Ensure that filtration systems are regularly maintained to maintain their efficiency.
- Combine filtration with other safety measures, such as proper ventilation and safe working practices.
- Consult technical specifications to understand the exact performance of the filter being used.
Technology for enhanced efficiency
Erlab specializes in filtration systems. Erlab’s ductless filtration fume hoods ensure optimal protection in diverse environments. Compliant with the most stringent standards, they safeguard both users and the environment, even in demanding conditions.
Enhanced safety with pre-filters
Each Erlab fume hood is equipped with a pre-filter, designed to maintain consistent filtration performance and ensure the safety of personnel. These pre-filters are integrated into every Erlab device (cabinets, air purifiers, etc.), and each unit is equipped with SMART technology, which alerts users when a filtration issue is detected.
Benefits for laboratories:
- Increased protection for users against harmful particles and vapors.
- Easy maintenance with intuitive tools and guided replacement protocols.
- A safer environment with filtration that meets the highest standards.
Myth: All filtration systems are equal
A common belief is that all filtration systems provide the same level of performance, but in reality, there is a wide variety of technologies designed for specific needs.
Reality: The differences between filtration technologies are significant. For example:
- Particulate filters: Effective for capturing fine particles but not suitable for chemical vapors.
- Activated carbon filters: Ideal for neutralizing volatile organic compounds (VOCs) but ineffective against solid particles.
- Hybrid systems: Combine multiple technologies to address a variety of needs.
Why does this matter? Choosing an inappropriate system can compromise safety and lead to unnecessary costs. A thorough assessment of the laboratory’s needs is essential.

Myth: Filtration is too expensive
The cost of filtration systems is often seen as a major barrier, especially for small laboratories. However, this perception does not consider long-term savings.
Reality : Although the initial investment may seem high, filtration systems lead to significant cost savings over time:
- Reduced energy costs: Filtration fume hoods consume less energy than traditional extraction systems.
- Lower maintenance expenses: Modern technologies extend filter lifespan.
- Reduced environmental impact: Ductless systems eliminate the need for large-scale air extraction, lowering energy consumption and preventing the release of harmful vapors outside the lab.
Many laboratories that have adopted filtration solutions report notable reductions in operational costs. Ajinomoto Omnichem, for example, has trusted Erlab’s GreenFumeHood filtration technology. Case Study
Myth: Filters require frequent replacement and high maintenance
Reality: Modern filters, such as those developed by Erlab, are designed for longevity and provide optimal performance throughout their lifecycle.
Advanced technology for extended lifespan
All Erlab devices are equipped with SMART technology, which monitors real-time filtration efficiency and alerts users when an issue is detected. This ensures continuous safety.
Myth: Extraction is more effective than filtration
Although extraction systems are widely used, they are not always the most effective or suitable—especially when ductless filtration solutions are available. Filtration offers significant advantages in terms of flexibility, safety, and sustainability.
Limitations of extraction:
- High energy consumption: Extraction systems require large volumes of air, increasing energy costs.
- Environmental impact: Extraction releases vapors outside, potentially causing local pollution if gases are not treated.
- Complex infrastructure: Installing extraction ducts often involves costly and invasive construction, making system relocation difficult when reorganizing lab spaces.
Advantages of filtration
- Localized protection: Contaminants are captured at the source, preventing their dispersion in ambient air and reducing exposure risks.
- Lower energy consumption: Unlike extraction, filtration does not require constant renewal of large air volumes.
- Flexibility and ease of use: Ductless fume hoods can be installed quickly without complex modifications and relocated as needed.
- Reduced environmental impact: Ductless filtration fume hoods do not release contaminated air inside or outside the laboratory.
Erlab’s added value: Compliance with strict standards
Erlab ensures its devices comply with the most stringent regulations to guarantee safety. Test Reports.
Maintenance and training: The keys to durability
Even the most advanced systems require regular maintenance and proper usage. Erlab supports laboratories with training programs and intuitive tools to maximize equipment performance.
Why maintenance is essential:
- Extends system lifespan.
- Ensures consistent efficiency.
- Prevents risks associated with improper use.
Conclusion: Separating fact from fiction
Filtration systems are powerful and valuable assets, but they are not magical solutions. Understanding their capabilities and limitations is crucial to maximizing their benefits. Additionally, selecting the right system with proper guidance ensures safety, efficiency, and long-term sustainability.
